Western Ranchers' Perspectives on Enablers and Constraints to Flood Irrigation
(2020-03)Flood irrigation on western rangelands is important for diverse social and ecological reasons, providing forage for many agricultural operations and maintaining many critical wetlands across the region. However, recent ... -
Phylogenetic Assessment of Freshwater Mussels Castalia ambigua and C. inflata at an Ecotone in the Paraguay River Basin, Brazil Shows That Inflated and Compressed Shell Morphotypes Are the Same Species
(MDPI, 2020-12-16)The phylogeny and taxonomy of freshwater mussels of the genus Castalia in South America is complicated by issues of morphological plasticity and limited molecular genetic data. We present field data on the distributions ... -
Are Road Crossings Fragmenting Populations of Clinch Dace?
(Humboldt Field Research Institute, 2020-11-16)Chrosomus sp. cf. saylori (Clinch Dace) is a newly recognized species of minnow with a restricted distribution in southwestern Virginia. We analyzed genetic variation and abundance at paired sites above and below road ... -
Exploring relationships among stream health, human well-being, and demographics in Virginia, USA
(Elsevier, 2020-12-09)Quantification of empirical relationships between ecosystem health and human well-being is uncommon at broad spatial scales. We used public data for Virginia (USA) counties to examine pairwise correlations among two ... -
Relationships between Pacific salmon and aquatic and terrestrial ecosystems: implications for ecosystem-based management
(2020-09)Pacific salmon influence temperate terrestrial and freshwater ecosystems through the dispersal of marine-derived nutrients and ecosystem engineering of stream beds when spawning. They also support large fisheries, particularly ... -
Gender Differences in Grant Submissions across Science and Engineering Fields at the NSF
(2020-09)There has been great growth in women's participation in the US academic doctoral workforce, but underrepresentation remains in all science and engineering fields, especially at high academic ranks. We obtained estimates ... -
Land use decisions after the Conservation Reserve Program: Re-enrollment, reversion, and persistence in the southern Great Plains
(2020-07-23)The temperate grasslands of North America remain one of the most modified and threatened ecosystems on the planet. In the United States, the conservation of grassland-dependent wildlife continues to be challenged by the ... -
Catawba Sustainability Center and Catawba Hospital Renewable Energy Site Planning Process Study
(Virginia Tech, 2020-09-29)The transdisciplinary Renewable Energy Facilities Siting Project produced a white paper outlining their proof-of-concept using a case study from the Catawba Valley. -
Transcriptomic and Metabolomic Responses of Rice Plants to Cnaphalocrocis medinalis Caterpillar Infestation
(MDPI, 2020-10-15)Interactions between plants and insect herbivores are important determinants of plant productivity in cultivated and natural agricultural fields. The rice leaf folder (Cnaphalocrocis medinalis) causes tremendous ... -
Epidemiology of dengue fever in Guatemala
(2020-08)Dengue is the most common mosquito-borne virus, and a major cause of fever, with an estimated 390 million infections annually. Guatemala, in Central America, has had ongoing dengue transmission since the 1990s. Its national ... -
Sex-specific effects of reproductive season on bobcat space use, movement, and resource selection in the Appalachian Mountains of Virginia
(2020-08-04)Across taxa, sex-specific demands vary temporally in accordance with reproductive investments. In solitary carnivores, females must provision and protect young independently while meeting increased energetic demands. Males ... -
Recent declines in salmon body size impact ecosystems and fisheries
(2020-08-19)Declines in animal body sizes are widely reported and likely impact ecological interactions and ecosystem services. For harvested species subject to multiple stressors, limited understanding of the causes and consequences ... -
Reconciling larval and adult sampling methods to model growth across life-stages
(2020-08-21)Individual growth rates are intrinsically related to survival and lifetime reproductive success and hence, are key determinants of population growth. Efforts to quantify age-size relationships are hampered by difficulties ... -
Drivers of a habitat shift by critically endangered Siberian cranes: Evidence from long-term data
(2020-09)Many waterbird populations have become increasingly dependent on agricultural habitats for feeding. While habitat destruction has been proposed as a key reason forcing waterbirds to move from natural habitats to agricultural ... -
Impact of exotic macroalga on shorebirds varies with foraging specialization and spatial scale
(2020-04-10)Exotic species may increase or decrease native biodiversity. However, effects of exotic species are often mixed; and indirect pathways and compensatory changes can mask effects. Context-specific assessments of the indirect ... -
An assessment of the niche centroid hypothesis: Pteropus lylei (Chiroptera)
(2020-05)Recent ecological theories propose that species reach their highest abundance and genetic diversity in the center of their ecological niche and decline toward the edges. We assessed whether Lyle's flying fox, Pteropus ... -
Exotic Prey Facilitate Coexistence between Pumas and Culpeo Foxes in the Andes of Central Chile
(MDPI, 2020-08-20)Coexistence between species with similar ecological niches implies species must segregate along one or more niche axes to survive. Space, time, and trophic resources are regarded as the principal axes upon which species ... -
Population Genetic Assessment of Anadromous and Resident Striped Bass (Morone saxatilis) in the Roanoke River System, Eastern United States
(MDPI, 2020-08-07)Striped bass is the subject of important commercial and sport fisheries in North America. The Roanoke River drainage—especially Smith Mountain Lake, Leesville Lake, and Kerr Reservoir—has popular recreational ...
